1. 2T Operation
>1. Press down button of torch, valve starts work, enter
pre-flow
stage.
>2. Setting time of pre-flow is end, machine output the setting
welding current.
>3. Release button of torch, machine stops work, but valve
keeps work, machine enter post flow stage.
>4. If
post flow
time is end, the valve stops work.
2. 4T Operation
>1. Press down button of torch, valve works, machine enter
pre-flow
stage.
>2. Setting time of pre-flow time is arrived, machine output
presetting
ignition current
.
>3. Release button of torch, machine goes up by setting
up
slope time
until up to setting current.
>4. Press down button of torch again, current goes down by
setting
down slope time
until up to the setting
crater
current
>5. Release button of torch again, machine stops work, but the valve keeps work, machine enter
post
flow
stage
>6. Setting
post flow
time is end, the valve stops work.
1.6.3. Parameter Setting
Under
TIG mode
, you can press button
Parameter to choose parameters, the
choosing parameters and corresponding
units can be watched on digital and units
sign parts (under TIG mode parameters
that can be chosen and parameters of
corresponding units see below table). Then
you can adjust chosen parameters by
adjustment of coding knob (adjusting range
of every parameter can be referred in the
parts technical parameters).
